The dramatic and climactic finales to the Mazda Road to Indy seasons, the Pro Mazda Championship Presented by Cooper Tires and Cooper Tires USF2000 Championship Powered by Mazda from Sonoma Raceway, air tonight on NBCSN at 2 a.m. ET.

It was a doozy on site, and will be recapped in a one-hour show this evening. Set your DVRs, or plan a marathon to stay up late.
